could be move to /proc/fs/jbd2/jbd2-debug, but it would require
some minor alterations to the jbd-stats patch.
This is also broken on the original jbd code.

But by using le32_to_cpu(es-s_blocks_count_hi) you explicitly mark the

Hi Laurent,
In this particular case though, the value of s_blocks_count_hi should not be
uses on its own. The correct way would be to use ext4_blocks_count() which

Set the journals JBD2_FEATURE_INCOMPAT_64BIT on devices with more
than 32bit block sizes during mount time. This ensure proper record

Hi Jose,
I'm sorry to reply so late, I had a day off yesterday.
I only tested the tools on an x86_64 system. Could it be an endianess issue?
On which platform do you run?

Correction,

Hi Jose,
thank you for the feedback.
We took your remarks into account and we are doing some perfs with
iozone (close to desktop activity, mono-thread) and ffsb (allows to run
benchs
in a multi-thread activity like a server does, different blocks sizes...).

Hi all,
we already discussed during the conf calls what
benchmarks should be ran on ext4.
As we have OLS paper on the table we were thinking
here at Bull what bench t run and on which kernel.
If we want trying to compare ext3 and ext4, I guess we
should at least show
